Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0023] Such as figure 1 , figure 2 , image 3 In the described embodiment, a pneumatic clutch booster includes a front cover 1, a rear cover 2, a diaphragm 3, a push rod, a spring 4, a push fork 5 and a hoop 6, and the rear cover 2 is provided with an air inlet 7, and the diaphragm 3 is installed between the front cover 1 and the rear cover 2. The front cover 1, the diaphragm 3 and the rear cover 2 are fixedly connected by a tight hoop 6, and the front cover A cavity is formed between 1 and the rear cover 2, and the diaphragm 3 divides the cavity into two parts. The rear cover 2 and the diaphragm 3 form an air pressure chamber, and the front cover 1 and the diaphragm 3 form a ventilation chamber. The push rod part includes a push plate 8 and a push rod 9, the front cover 1 is provided with a through hole 10 for installing the push rod 9, th...

The air pressure type clutch booster has the advantages that the air pressure type clutch booster can be realized only by the aid of the air pressure, and is simple in structure, convenient to operate, low in manufacturing cost, fine in sealing effect and long in service life.
Description
technical field [0001] The invention relates to an external clutch control device, in particular to a pneumatic clutch booster. Background technique [0002] At present, in the clutch control system of heavy-duty vehicles, large passenger vehicles and construction machinery vehicles, due to the heavy force of the clutch pedal, it is impossible to cut off the power conveniently and easily, and it is impossible to easily shift gears. In order to reduce the fatigue of the driver and ensure driving safety, Therefore, it is usually necessary to install a clutch booster between the clutch and the clutch master cylinder, and use the compressed air source of the vehicle to provide boost for the clutch. However, at present, many clutch boosters have complex structures and high costs. There are various oil passages in the booster housing, and the pneumatic cylinder and hydraulic cylinder are integrated structures, which are not easy to process and high in cost.
